Answer:
1 1/2 + (-1/2) is also 1 1/2 - 1/2.
the result is 1 whole, and 1 whole is also the difference between 1 1/2 and 1/2.
Say you have half of a cheese piece, but your friend has 1 whole cheese piece plus half of a cheese piece.
He/She has 1 more cheese piece than you, right? That's the difference between you and your friend's cheese. 1 whole.
Answer:
Angel two measures 60.4.
Step-by-step explanation
Since you are given one number, you would just have to subtract that from 90. (Easiest way to explain) Complementary angels are when the sum of both angels add up to 90°.
Let i = sqrt(-1) which is the conventional notation to set up an imaginary number
The idea is to break up the radicand, aka stuff under the square root, to simplify
sqrt(-8) = sqrt(-1*4*2)
sqrt(-8) = sqrt(-1)*sqrt(4)*sqrt(2)
sqrt(-8) = i*2*sqrt(2)
sqrt(-8) = 2i*sqrt(2)
